Milk is packed with calcium and protein and is also a necessary ingredient in many recipes. It’s something that you’ll want to have on hand in a survival situation. However, milk doesn’t keep long, especially if you don’t have any means to refrigerate it.
You definitely want to include milk in your emergency storage. Maybe you have a milk cow or goat that produces more milk than you can use before it goes bad. Since cows and goats both have drying out periods so you’ll want to preserve milk for then, too. But what can you do to make it last?
Today we’re going to talk about several methods of either preserving milk as-is or converting into other products that store for longer periods of time. Before we get started, we’d like to offer a few tips.
Before you start any preservation methods at all, pasteurize your milk. I know that many people prefer to drink their milk straight from the cow but the idea behind preservation is to keep bacteria from turning the milk bad. If you filter and pasteurize it, you’ll be starting with “clean” milk that will be more likely to keep longer. This is, of course, up to you but I advise it.
Salting is important to the preservation of anything and that includes your milk products.
Though you probably don’t want to salt your milk before you can it, you definitely want to salt your butter, cottage cheese and other products.
This will not only help them last longer but will also give you access to a food in your emergency food supply that has that necessary mineral (and flavor enhancer) in it.
If you’ve dehydrated other foods, it may have occurred to you that you could do the same with milk. As bad as I hate to burst your bubble, it’s not so easy to do if you want to preserve the flavor and nutritional value. You also need to have special equipment such as an atomizer that won’t come cheap. You will also need a ton of milk just to yield a pint of dehydrated milk. Skip this idea and just buy powdered milk.
Yes, it’s entirely possible to freeze milk but I recommend not doing so for a couple of reasons. First, if SHTF you probably won’t have the electricity to keep the freezer running so your milk will go bad within a couple of days, especially if it’s hot outside.
Second, frozen milk is fine to use but it often gets a grainy texture to it. It separates out but that can be dealt with just by shaking it up. Still, the texture thing is an issue and is the main reason that I don’t recommend freezing it for everyday use.
We’ve discussed canning in other articles but many people don’t realize that milk can be canned, too. Just as with all canning procedures, it’s imperative that you make sure that your jars and seals are super clean. Warm your seals if necessary in order to get the best seal possible.
To can milk, start with extremely clean milk. Clean the udder, the buckets and all the equipment in addition to the jars. As I already stated, I recommend pasteurizing, too. At the very least, strain it well using a milk sieve or several layers of clean, lint-free cloth such as cheese cloth. Pour the milk into a clean bowl and cover it so that nothing gets into it while you’re prepping the jars.
Wash your jars in hot, soapy water and rinse them well. Keep them submerged in hot water until you’re ready to use each them.
Fill each jar with milk, leaving a half-inch at the top for headroom. Clean the rims of the jars thoroughly and put the sterilized hot rims and rings on them. Put them in your pressure canner and fill with the recommended amount of water. Place the canner over the hottest part of the stove, on about medium.
Bring the pressure to 10 and cook quarts for 25 minutes or pints for 20 minutes. Make sure the pressure stays at 10 or else you’ll need to start the time over.
The reason that I gave you directions for using a pressure canner is because milk is a low-acid food and is therefore susceptible to botulism found in the soil. Pressure canning brings the milk up to a safe temperature and holds it at that temperature long enough to kill any bacteria.
Canned milk will keep up to 2 years and is great for cooking and even drinking though the color will change. It will have a slight caramel color and may taste a bit sweeter or just cooked. Canned milk is great for any recipe that requires milk; however, you can’t make cheese, yogurt or rennet desserts from it because the milk won’t clabber.
One of the problems of storing canned whole milk is space. Even though you can buy canned milk at the store, there’s no guaranteeing what goes into that milk. Also, there’s no need to waste all of that fresh milk that you’re getting from your cows or goats on a daily basis. That’s where condensing your own milk comes in.
Evaporated milk is simply whole milk that has had about 60% of the water removed from it and you can do it at home as long as you pay attention. Here’s an easy way to do it.
Start with 4 ½ cups of milk. Feel free to double or triple this if you’d like, then do the math for the process. It’ll work just fine.
- Pour two cups of the milk into a heavy-bottomed pan.
- Stick a wooden spoon into the milk, holding it straight up and mark where the milk level is.
- Pour the rest of the milk into the pan.
- Bring the milk to a simmer, stirring every couple of minutes to make sure that it doesn’t singe.
- Remove the skin that forms as the milk reduces.
- Use the spatula to measure your progress. When the level of the milk reaches the mark you made, the milk has reduced 60 percent and is done.
- Allow to cool then follow the canning procedures described above for canning whole milk.
Evaporated milk can be reconstituted by adding equal amounts of water to it or it can be used as-is in recipes such as puddings or to give coffee, tea or cocoa a rich flavor. It keeps about as long as regular canned milk does and takes up half the space.
